- CCA corrected covered area, NA not applicable, SR systematic review
- aFor Cochrane SRs we used the year last assessed as up-to-date
- bEach primary study was counted only once, regardless of how many SRs included that study
- cCategorized using published criteria as “slight” (0–5), “moderate” (6–10), “high” (11–15), or “very high” (> 15)
